I filter my water through 90-plus feet of sand, hardpan, and a couple inches of topsoil. Yep, I have a well. The water is absolutely wonderful, but a little hard. I don't have a problems with calcium scale in any of my appliances or on my pots and pans, or even in the toilet bowl. But it does tend to gum up the works on one of my temperature compensating shower faucets (I have 3 bathrooms in this home). I have to shell out about 90 bucks to replace one that I broke while trying to dissasemble it, so that I could clean off the scale deposits. Some day, I should really get a water softener (heavy sigh).
